7084 upper gastrointestinal tract endoscopies in the years 1973 to 1981 revealed 1664 duodenal or gastric ulcers. The number of total ulcer observations in relation to specific months differed between 110 in the 9 June periods and 189 in the 9 October months. A convincing peak was not detected. However, the number of ulcers per month or per season was not distributed evenly, as judged by chi-Square analysis. 30% of all ulcer observations occurred in the fall, 24% in the winter, 24% in the spring and 22% in the summer. Our material did not reveal, whether the slight increase in the fall reflected a true rise in the ulcer incidence or whether it had to be attributed to seasonal variations in referrals for endoscopic examinations. Nevertheless the reported data are further evidence for the perennial rather than seasonal nature of gastroduodenal ulcers.
1973年至1981年间的7084例上消化道内镜检查发现了1664例十二指肠溃疡或胃溃疡。与特定月份相关的溃疡观察总数在6月的9个时间段为110例，在10月的9个月份为189例，两者存在差异。未检测到明显的峰值。然而，根据卡方分析判断，每月或每季度的溃疡数量分布并不均匀。所有溃疡观察病例的30%发生在秋季，24%发生在冬季，24%发生在春季，22%发生在夏季。我们的资料并未表明，秋季的轻微增加是反映了溃疡发病率的真正上升，还是应归因于内镜检查转诊的季节性变化。尽管如此，所报告的数据进一步证明了胃十二指肠溃疡的常年性而非季节性特征。
